Brief Summary:
This is an exploratory study to determine the safety and clinical benefit of OMS302 Injection in subjects undergoing Cataract Extraction with Lens Replacement (CELR) using a coaxial phacoemulsification process.

Condition or disease Intervention/treatment Phase
Cataract Extraction Drug: OMS302 Drug: OMS302-PE Drug: Vehicle Phase 1 Phase 2

Detailed Description:
OMS302 Injection is a mydriatic/anti-inflammatory combination investigational drug product being developed as an irrigation solution during intracameral lens replacement surgical procedures of the eye. OMS302 irrigation solution may induce and maintain an adequately dilated pupil and reduce postoperative symptoms of discomfort such as eye pain and irritation. The use of OMS302 irrigation solution may eliminate the need for pre-operative dilation of the eye and could reduce the postoperative use of an anti-inflammatory and pain medications following surgery.

  • Subject who is taking medications with the same activities as that of the active ingredients in OMS302 for defined time intervals prior to and after surgery.
  • Female subject of childbearing potential (i.e., not surgically sterilized nor post-menopausal longer than one year) who is not using an effective method of birth control within at least 14 days prior to surgery or has a positive pregnancy test.

  • Subject that has uncontrolled chronic ocular disease.
  • Subject that has active corneal pathology or scarring noted in either eye (except superficial punctate keratopathy in the non-study eye).
  • Subject that has extraocular/intraocular inflammation in either eye.
  • Subject has an active bacterial and/or viral infection in either eye.
  • Subject that has narrow-angle glaucoma, unstable glaucoma, or glaucoma being treated with prostaglandins or prostaglandin analogues.
  • Subject taking, or has taken within the past year, an alpha adrenergic antagonist.
  • Subject that has participated in or is currently participating in any investigational drug or device trial within the previous 30 days prior to the day of surgery.
  • Subject that has had intraocular conventional surgery within the past three months or intraocular laser surgery within one month of the planned surgery in the study eye.
  • Subject that requires the use of other topical medications during the trial except prophylactic antibiotics, topical lid care or glaucoma medications or tear replacement solutions.
  • Subject that needs other ocular surgery at the time of the cataract extraction.
